According to a statistical analysis of the 2011 surveillance data from the National Tumor Registry, 3.37 million new cancer cases were diagnosed in China in that year. Meanwhile, the 2014 annual report of tumor registry shows that the chance of a person getting a malignant tumor in his or her lifetime is 22%. This is equivalent to 6.4 people getting cancer every minute, and each person has nearly 1/4 of the potential to get cancer. As of today, lung cancer is still the number one malignant tumor in China in terms of incidence and mortality. What does this number mean? More than 60% of patients in China are found too late Such a newly released transparent data triggers everyone’s attention; from the perspective of ordinary people, it means to develop good living habits and pay attention to targeted medical checkups to prevent cancer. So, what does this figure really mean? In the summit interview of cancer prevention and control in China, the president of cancer hospital, Herje, still showed his regret – cancer prevention and control is divided into three stages: education, early diagnosis and treatment, and treatment and diagnosis, while 60% to 80% of their patients are already in the middle and late stages when they first arrive at the hospital. The first is that they do not know about cancer and do not find it in time; the second is that they find some symptoms or some early manifestations but do not care about them. In fact, the incidence rate of tumor in China is still relatively low in the world, but the cure rate is also relatively poor, one of the reasons is late detection. How is this figure arrived at? Combined with statistical data estimation Professor Chen Wanqing of National Office of Cancer Control analyzed that according to the data reported by project sites distributed all over the country, 3.37 million new cancer cases were reported in 2011, an increase of 280,000 compared to 2010 – which is equivalent to 6.4 people getting cancer every minute. The reported data of more than 300 project sites covering more than 300 million people actually used 177 project sites covering about 170 million people, which is a large enough sample size. Based on this data, estimates were made by combining the national population. There are almost 300,000 more people a year, but actually the overall incidence rate does not change too much considering the population growth and aging. Herger also mentioned that 1/3 of cancers can be prevented, 1/3 can be cured and 1/3 can be in remission. People should neither talk about cancer, nor pay attention to changing their lifestyles and targeted checkups, most malignant tumors have a latent time of 10 to 15 years to correct, so don’t miss this opportunity. In addition, Chen Wanqing believes that the transparency of information, although it may cause some misinterpretation, is still beneficial to the health awareness of all people. What do authoritative experts think? Some chemicals are related to cancer Nowadays, more and more people are concerned about cancer, but we also notice that there are more and more cancer prevention and health programs or internet posts, how much credibility is there in them. What do the authoritative experts think about this? The theme of this “Cancer Prevention and Control Week” is “Scientific Understanding of Cancer and Healthy Living”. Herger said that there is no clear research to prove what food can cause cancer, but he made a suggestion based on the available statistics. Some chemical substances are related to cancer, such as some pickles, sauerkraut, nitrosamine compounds extracted from meat, these compounds are directly related to cancer, so in this sense, foods that are related to these compounds are considered to be related to cancer and should be kept away from as much as possible. For example, I don’t eat overnight cabbage. After overnight, it has high nitrosamines and nitrites content. Is it reliable to prevent cancer in the community? To focus on dietary balance Wang Greenhua, vice president of the Cancer Hospital of the Chinese Academy of Medical Sciences, said, do not smoke, drink less, many people’s ears may have heard a callus, many people may be prone to be a little lazy, such as a certain program said, to eat sweet potatoes, can prevent cancer, many people go in a flock to buy sweet potatoes. Is this reliable? To focus on a healthy lifestyle, dietary balance, not just say what is good to eat, not what is good. I noticed a statement that sweet potatoes are healthy food, anti-cancer food. You may not know, 30 years ago, some northern rural areas, sweet potato is a staple food, because it is sugar, stomach acid production, gastric ulcer, duodenal ulcer incidence quite a lot. Of course, we have a certain proportion of sweet potatoes and mixed grains in our dietary structure, which may be beneficial to health.
